IMPROVEMENT IN CbMBlNEU-PUMPS AND SlPHONS."

The Schedule referred to in these Letters Patenuand making part of the name Be it known that we, JOHN D. AVERELL and GEORGE A. HIGGINS, of the city and State of New York, and THOMAS GORDON, of Shrewsbury, in the county'of Monmouth and State of New Jersey, have invented and made a new and useful Improvement in Siphons; and the following is hereby declared to be a;

correct description of the same.

.In the. construction of siphons' it has been usual heretofore to make use of a mouth-tube running up from the longest'leg of the siphon, so that the. air can be exhausted to cause the liquid torflow. v

.. In siphoning many liquids, such as Oils, acids, 860., it is very' disagreeable, and sometimes dangerous to health to exhaust, the siphon by the mouth, and when the vessel is filled from the siphon, that has to be lifted to cause air to pass in and stop the flow, or else a cock has to be employed to shut off the flow.

, stop-valve, whereby the siphon can be exhausted and made to flow by the action of the pump, or the piston of the said pumpvcan be used as a stop to arrest the flow of liquid in placeot' a cook, or the siphon can be used as a pump in cases where 'the differences in the level of the liquids in the receiver and container are snch that the siphon will not act.

In the drawing we have *shown a sectional view of Ourcombinedsiphon, pump, and stop-valve, in which-- a b are the legs of the siphon of any usual charactially as set forth.

phon, and in this is a piston, d, actuated by a rod, 0.

These valves might be placed at the bottom of the cylinder 0, so as to be-made Offpliable leather, that will not interfere with the flow of liquid througlr the seats when the apparatus is acting as a siphon,

"It is now to be understood that the pump, formed of the rod 0, piston 11, and cylinder 0, is to be used to exhaust the siphon, and-that the liquid will flow through said siphon and be delivered at the nozzle h, and, when the piston 41 is forced down, it will act as a stop-valve by cutting offthe passage between the leg I) and exittube h.

. If the siphon will not-act, the pump can be used to draw and eject the liquid regardless of the relative levels of the liquid in the container and receiver.

We claim as our invention The pump 0 d e and valves t and o,combined with i the siphon a b, and arranged substantially as specified,

so that the piston d willact as a stop to the siphon, and the siphon can also be used as a' pump, substan- Signed by us this 3d day of January 1870.
